Intracranial Nasal Dermoid Sinus Cyst: Transnasal Endoscopic Resection by Open Rhinoplasty Approach, With Intraoperative Video.

Nasal dermoid sinus cysts are rare congenital lesions that may lead to recurrent soft tissue infections and severe intracranial complications. In case of an intracranial extension, the traditional surgical approach includes a frontal craniotomy with significant morbidity. As a less invasive alternative, a transnasal endoscopic approach has been recommended. This report describes the transnasal endoscopic resection of an intracranial nasal dermoid sinus cyst via an open rhinoplasty approach, which achieved a wide surgical exposure with minimal invasivity and ideal aesthetic results. An intraoperative video demonstrates this combination of techniques in this rare skull base/intracranial pathology. (C) 2016 by Mutaz B. Habal, MD.
